We investigate the scaling law of throughput capacity of hybrid networks with non-trivial node mobility. By non-trivial mobility, we mean it is strong enough to improve capacity. A general model with heterogeneous nodes and spatial inhomogeneities is adopted. We show in a network, whose physical extension grows at f(n), with n users and k base stations, the per-node capacity is ??(1/f(n)) + ??(k/n)...
A mobile ad hoc network (MANET) is a collection of mobile nodes that communicate and collaborate with each other without reliance on any pre-existing infrastructure. In MANETs, wireless links are subject to frequent breakages due to nodes high mobility. While several routing protocols such AODV and DSR have been designed for MANETs, many of operate efficiently under low network mobility conditions...
In the area of mobile ad hoc and sensor networks, simulation became the evaluation method of choice. Due to the high number of variables - including transmission range, number of nodes, simulation area, mobility pattern-simulation settings vary largely from work to work, depending on the application scenario focused. The results for two simulations with identical setting, but different mobility models,...
All validations of MANET simulations are meaningful when they use realistic mobility models. If this movement is unrealistic, the simulation results obtained may not correctly reflect the true performance of the protocols. The majority of existing mobility models for MANET do not provide realistic movement. Most of the mobile nodes are directly or indirectly handled by human beings so mobility model...
Most of the MANET protocols are evaluated by simulation environments. The validation is meaningful when they use realistic mobility models. Once the nodes have been initially distributed, the mobility model dictates the movement of the nodes within the network. If this movement is unrealistic, the simulation results obtained may not correctly reflect the true performance of the protocols. The majority...
